Then you go into group policy management. Expand to forest: domain.local -> domains -> domain.local -> Group Policy Objects. Right click on Group Policy Objects and choose NEW. Give it a name like "map DC drives" and hit OK. Right click on the new group policy object you just created and choose EDIT. Expand User Configuration -> Preferences -> Windows Settings. Right click on Drive Maps and choose New -> Mapped Drive.
Create the drive and location as specified like this.
Still in group policy management , right click on the OU you want to apply the group policy to and click "link to existing GPO." Choose the appropriate group policy.
Now, any users you have in that OU will have that group policy that maps network drives applied to them.
At the end, run "gpupdate /force" from an elevated command prompt.
